AR Glasses Offload Processing to Server via 5G
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality (AR) glasses face power consumption issues due to processing-intensive tasks, leading to short battery life and bulky designs, especially when used in applications like automotive navigation where real-time data processing is required.
Innovation Solution
Shifting processing tasks from AR devices to a back-end computer server via a low-latency wide area network, such as a 5G network, to offload complex computations and reduce power consumption, allowing for longer battery life and more compact designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If processing tasks are performed locally in AR glasses, then real-time processing capability is improved, but power consumption increases and battery life decreases
Solution Approach 1:
The patent extracts processing tasks from the AR glasses device and relocates them to remote servers. The AR glasses retain only essential functions (capturing reality data and displaying AR data), while complex processing is performed externally, thereby reducing local power consumption while maintaining real-time processing capability through networked computation.
Solution Approach 2:
The patent introduces a communication network as an intermediary between the AR glasses and processing servers. This intermediary enables distributed processing where computation can be performed remotely and results transmitted back, allowing the AR device to access high-processing-power resources without carrying large batteries.
2Duration of action of moving object
If a large battery package is used in AR glasses, then operating duration is improved, but device weight increases and design becomes bulky
Solution Approach 1:
The patent extracts the battery power requirement from the AR glasses by moving processing tasks to external servers. This eliminates the need for large battery packages, reducing device weight and enabling sleeker designs while operating duration is effectively extended through cloud-based processing availability.
3Use of energy by moving object
If processing tasks are offloaded to external servers, then power consumption is reduced, but network dependency increases and real-time performance may be affected
Solution Approach 1:
The patent designs the AR system to support multiple operational modes: full cloud processing, hybrid processing, and local fallback. This multi-functionality ensures that the system can adapt to different network conditions and maintain real-time performance reliability even when network connectivity is intermittent, while still achieving power consumption reduction through server offloading.
